The Zotac GeForce GTX 1070 offers great performance at a relatively low price, making it a strong contender for the best partner card in terms of performance.

There are other factors to consider however, as some partner cards may employ quieter coolers, use less power, and generate less heat than others.

The Nvidia GeForce GTX 1070 Founders Edition is the worst product in relative performance, and should not be bought unless you plan to use a custom cooler and overclock the GPU (or you prefer the look of Nvidia’s blower fan cooler).
